وَاِذَا كُنۡتَ فِيۡهِمۡ فَاَقَمۡتَ لَهُمُ الصَّلٰوةَ فَلۡتَقُمۡ طَآٮِٕفَةٌ مِّنۡهُمۡ مَّعَكَ وَلۡيَاۡخُذُوۡۤا اَسۡلِحَتَهُمۡ فَاِذَا سَجَدُوۡا فَلۡيَكُوۡنُوۡا مِنۡ وَّرَآٮِٕكُمۡ ۖ وَلۡتَاۡتِ طَآٮِٕفَةٌ اُخۡرٰى لَمۡ يُصَلُّوۡا فَلۡيُصَلُّوۡا مَعَكَ وَلۡيَاۡخُذُوۡا حِذۡرَهُمۡ وَاَسۡلِحَتَهُمۡ ۚ وَدَّ الَّذِيۡنَ كَفَرُوۡا لَوۡ تَغۡفُلُوۡنَ عَنۡ اَسۡلِحَتِكُمۡ وَاَمۡتِعَتِكُمۡ فَيَمِيۡلُوۡنَ عَلَيۡكُمۡ مَّيۡلَةً وَّاحِدَةً ؕ وَلَا جُنَاحَ عَلَيۡكُمۡ اِنۡ كَانَ بِكُمۡ اَ ذًى مِّنۡ مَّطَرٍ اَوۡ كُنۡـتُمۡ مَّرۡضٰۤى اَنۡ تَضَعُوۡۤا اَسۡلِحَتَكُمۡ ۚ وَ خُذُوۡا حِذۡرَكُمۡ ؕ اِنَّ اللّٰهَ اَعَدَّ لِلۡكٰفِرِيۡنَ عَذَابًا مُّهِيۡنًا(النساء :102)

Sahih International:
And when you are among them and lead them in prayer, let a group of them stand [in prayer] with you and let them carry their arms. And when they have prostrated, let them be [in position] behind you and have the other group come forward which has not [yet] prayed and let them pray with you, taking precaution and carrying their arms. Those who disbelieve wish that you would neglect your weapons and your baggage so they could come down upon you in one [single] attack. But there is no blame upon you, if you are troubled by rain or are ill, for putting down your arms, but take precaution. Indeed, Allah has prepared for the disbelievers a humiliating punishment.
يٰۤـاَيُّهَا الَّذِيۡنَ اٰمَنُوۡا خُذُوۡا حِذۡرَكُمۡ فَانْفِرُوۡا ثُبَاتٍ اَوِ انْفِرُوۡا جَمِيۡعًا(النساء :71)
Ya ayyuha allatheena amanoo khuthoo hithrakum fainfiroo thubatin awi infiroo jamee'an
Sahih International:
O you who have believed, take your precaution and [either] go forth in companies or go forth all together.
